I think it's the human psychology, how people get stuck in a situation but overcome from it. Also as a marketer I've learnt it's an excellent idea to reach more people those who are our targeted audience.
I'm thankful I didn't lose my Job.
The pandemic didn't affect me because for 13 year due to health problems, I have practically been on lockdown (apart from going to work), also my Brother dies a month before the pandemic Feb 2020. I was glad to work from home, i had been angling to WFH for ages.
Putting things in perspective. Sometimes I went crazy at home because I felt like I was falling behind on work and not being productive. But I learned to zoom out a bit sometimes and ask myself "what happens, if I don't finish this right now, but tomorrow when I'm more rested?" And usually the answer is: "Nothing". It is barely ever business critical and we often just want to live up to our own quality standards. And working from home, we feel like we need to prove that we are being productive and that also puts a lot of pressure on us.
The most valuable lesson I learned while working during a pandemic is that always have a contingency plan. Even though I have a plan before the pandemic happened, I hope that many people would start having a backup plan for their foreseeable future.
